IDEST Regulator Servicing Course

Why take this Regulator Servicing course?

Regulators are life-support equipment. Proper servicing requires documented processes, correct tools and measured performance. This workshop builds repeatable competence to service common first and second stages in line with IDEST methodology and manufacturer manuals, so regulators go back to divers safe and in spec.

Who it’s for

• Service technicians formalising skills and documentation

• Club equipment officers maintaining member kit

• Centre owners/managers building in-house service capability

• Technically minded new starters entering servicing

What you’ll learn

• Standards & documentation: IDEST overview, service intervals, warranty kits, serialisation, job cards & audit readiness

• Tools & setup: torque wrenches, IP gauges, magnehelic/manometer proxies, flow meters, ultrasonic cleaners, bench safety

• First stages: piston/diaphragm, balanced/unbalanced, environmental sealing, filters/seats/springs, HP/LP port care

• Second stages: demand valves, lever height, orifice/seat, cracking pressure, Venturi & dive/pre-dive controls

• Disassembly & cleaning: degreasing, ultrasonic technique, inspection under magnification, measuring wear & corrosion

• Parts & materials: OEM kits, O-ring selection, oxygen-compatible lubricants (where specified), what not to use

• Reassembly & torque: seals, shims, torque values, lock-outs and thread care

• Testing & tuning: intermediate pressure set-up, stability & creep, cracking effort setup, leak checks (HP/LP), purge/flow tests, cold-water considerations

• Oxygen service considerations: cleanliness boundaries, when full O₂ cleaning is required, labelling & paperwork

• Records & customer care: service reports, stickers, next-service reminders, test results retention
